Direct Metal Laser Sintering / Selective Laser Melting (DMLS/SLM)
The technology of laser sintering of metal powder works by melting fine metal powder with a heat source generated by a focused laser beam. There are single-laser as well as multi-laser systems (an even number, such as 2 or 4) to increase productivity. The fine metal powder is placed in a containerโthe main reservoir. The entire process is carried out in a special protective atmosphere (nitrogen or argon) to ensure safe production and to prevent the powder from oxidizing.
After scanning the cross-section of one layer, the laser stops, and the main reservoir lowers by the height of one layer, which is typically 0.05 mm. Then, new powder from a secondary feed reservoir is added to this height, evenly spread, and compacted to the required density. The whole process is then repeated until the part(s) are printed to the desired height.

BJ (Binder Jetting)
Binder Jetting can work with various types of input materials. In addition to metals, it is also used for producing plastic and ceramic parts. The input material is in powder form.
The metal powder is placed in a containerโthe main reservoir. However, the print head, instead of sintering (as in the DMLS/SLM technologies), applies a binder, i.e., a substance that โgluesโ loose powder particles in the desired cross-section of a single layer. After scanning the cross-section of one layer, the print head stops applying the binder and the main reservoir lowers by the height of one layer, which is typically 0.1 mm. Then, new powder from a secondary feed reservoir is added to this height, evenly spread, and compacted to the required density. The whole process is then repeated until the part(s) are printed to the desired height.

DMLS/SLM Technology Materials
Stainless Steel 316L
Universal corrosion-resistant steel (surgical steel).
Aluminum Alloy AlSi10Mg
A popular material due to its low weight and high strength.
Tool Steel MS1
Steel with high strength and the ability to be heat treated, similar to conventional steels.
